Canadian PM Justin Trudeau crashes school prom photo

It's hard to imagine these kids being more excited over any other celebrity crossing their paths at this particular moment.

Maybe former US President Barack Obama, when he was in office?

Or Justin Bieber, but just for the girls?

Instead, arguably the biggest celebrity crowd pleaser of all time — Canadian Prime Minister Justin Trudeau - just happened upon a group of excited teenagers taking photos for the high school prom.

And because he is one of the most personable politicians in the whole entire world, he stopped to take a photo with them.

Like prom night wasn't exciting enough before Trudeau appeared.

Here's how this now famous moment unfolded.

At first, Trudeau was just another bloke jogging along the Stanley Park Seawall, being followed by official photographer Adam Scott who Tweeted a photo of well-dressed teens milling about, commenting, "Prom season in #Vancouver".

Then some of those teens looked up and recognised their Prime Minister sweating it out, about to pass right by them.

One of those teens, Constantine Maragos, told CBC Canada, "We were just taking photos and hanging around talking, and then Trudeau, he just comes running.

"At first, we were like, 'Why is the prime minister of Canada running the seawall? And then we started yelling for Trudeau to get in the photo."

Which he happily did. The moment was captured by prom photographer Cameron Corrado and posted on his official Instagram account shortly after.
